Power Option Problems

I am trying to be "Greener" and have set my Power Options to Turn off as follows.Monitor 10 MinutesHD 30 MinutesStandby 30 MinutesHibernate 1 Hour(Enable Hibernation is ticked)Nothing happens at all, I did a search in the forum and it seems others have the same problem, but no solution click hereI am on XP Pro SP2 all up to date. Any further ideas please

I couldn't find anything like "let op system handle power options" but I have changrd 2 settings which I thought may be similar. "Remote Wakeup" was OFF, now turned ON. "AC Power Recovery" was OFF, now is On. I do not really understand either setting so if you have further advice I am ready to listen. I will leave the computer alone now and see if it has made a difference.

You should keep settings like Remote wake-up off. There are two kinds - one that wakes the PC from a signal through the Ethernet LAN port and one that wakes it from a dial-up modem. If you have either of these in use, it's best to keep that feature disabled. It sometimes results in your PC waking up when you didn't ask it to.

Forgot to add that you may want to check for motherboard driver updates. Although, if my memory's right, you haven't had this PC for very many months? So the drivers are probably not at fault unless you have what was at the time a new motherboard model.

Thanks for that, I have put all the settings back to how they were (ie OFF) I will check the motherboard drivers as the computer is over 4 years old and those drivers have never been updated.I am going out this evening so it will be tomorrow before I can check, I will report back.

I can't find anything in BIOS that would seem to be related regarding power I only haveAuto Power On/ DisabledRemote Wake Up OffAC Power Recovery OffFast Boot OnSuspend Mode says S3 the only alternative is S1 and I have no idea what either of these mean.I have been unable to find driver updates.
